title: Association of the CTG (-2578/-460/+405) haplotype within the vascular endothelial growth factor gene with early-onset psoriasis.
abstract: Polymorphism of vascular endothelial growth factor (VEGF) influences the VEGF production and is subjected to genetic susceptibility of many diseases including psoriasis. Three single nucleotide polymorphisms (SNPs) within the promoter and exon 1 region [-2578(C/A), -460(C/T) and +405(C/G)] were analyzed in 154 patients with chronic plaque psoriasis and in 234 ethnically matched healthy controls from Thailand. The CTG (-2578/-460/+405) haplotype frequency was higher in patients with early-onset psoriasis (44.12%) compared with healthy controls (33.33%) (odds ratio = 1.54, 95% confidence interval = 1.08-2.18, P = 0.016, corrected P value: P(c) = 0.048). The results suggest that the CTG haplotype can be used as a genetic marker for psoriasis especially the early-onset group of Thais.
